Looks like you got it (Cheap trick for DOF i use)
Take a look in the red is where i want the DOF so to do this quickly without taking the time to using the pen mask tool what i do is Dupe the pic Add Gaussian Blur and then get the Eraser Tool and lower the Opacity and hit the nearest part of the car with it that way we have DOF in the distance and clear up close Now there are problems with this method seeing as the Eraser tool isnt the best for small area theres bond to be some mess ups some where but its faster than using the pen tool give it a try it might help ya in the long run! P.S you can obvy clean it up with the Pen tool after to get it Crisp
